Evaluate using Cauchy’s Integral Formulae, where C is a square with sides of length 4 centred at the origin: integral: cos(z)/(z-1)^4

haha, now youre doing math!!!

whats the cauchy integral formula, is it with the line integral business

its the integral f(z)/z-w where you choose f(z) and w

I'm not sure what to choose as f(z), w=1 as there is a singularity at 1

right, a pole one sec

what class is this?

2nd year undergrad maths :P

wow

in america?

nope...uk

ahh

you know how to figure it out?

no

This is complex analysis. I know how to figure it out, but I'm currently busy at the moment.

hanky, where i can learn complex analysis

without all the formal rigorous stuff. an intuitive approach

Hmm... I can't really say. There are a few textbooks out there that'll teach you theory... you could just look through them and figure out the computational part of it.
